I never understood just how good this lil guy was until I got Stitches Jr. at my Pet Menagerie and couldn't figure out how to get this thing killed. I could get Stitches killed the first time but since he was Undead he'd rez up and kill my last guy. I would start off with my Mini Mindslayer and use Life Exchange and then Inner Vision then swap out pets (Had an Unborn Val'kyr and Chrominius as my other 2 pets). After Unborn was dead I brough back the Mini for round of the same bring him back to full health then swapping for the Chrommy for the final blow for first death. What was great was when Stitches revived I had and almost fully healed Mini Mindslayer who just had to survive one hit (less than 500) and I won. I should try him with that kid over on Timeless Island!

Going with Mana Surge you will be cooldown locked. If you chose not to use Mana Surge then this little guy won't do any real damage at all. Pretty decent stats, and Mana Surge can do some real damage. But be prepared to switch around a bit since otherwise you will just stand around doing nothing useful for quite a while. I would suggest finding your Mana Surge fix somewhere else. The other attacks do very little damage, even if buffed by amplify magic.

This pet can be difficult to get for casters, as the boss will interrupt pretty much any cast time. Instant casts and melee are the way to go. But for Shamans, don't use totems as multiple targets will cause him to mind control you and then reset.

Confirmed that this drops off The Prophet Skeram. I've noticed that all the raid pets don't have a 100% chance to drop. I had two drop in MC, zero drop in BWL. I've only killed Skeram once. I can only assume AQ and Naxx go by the same rules as MC and BWL.
